Answer:

3x = 12x - 81(vertically opposite angles)

→3x - 12x =  - 81

→- 9x =  - 81

→x =  \frac{ - 81}{ - 9}

→x =  \frac{81}{9}

→x = 9

hope it helped you:)

3y - 5z = -23
leonid [27]
Starting off, we can multiply the third equation by 2 and add it to the third to get rid of both the x and y variables. Next, we get z=1. Plugging that into 3y-5z=-23, we get 3y-5=-23. Adding 5 to both sides, we get 3y=-18. After that, we can divide both sides by 3 to get y=-6. Plugging that into -2x-y-z=-3, we get -2x+6-1=-3=-2x+5. Subtracting 5x from both sides, we get -2x=-8. After that, we can divide both sides by -2 to get x=4.

<span>Given that the average time it takes to replace a defective car radiator is 70 minutes with a standard deviation of 12 minutes.

The 90% confidence interval of a random sample of 50 is given by

90\% \ C.I.=70\pm1.645 \frac{12}{\sqrt{50}}  \\  \\ \Rightarrow 70+1.645 \frac{12}{\sqrt{50}} \ and \ 70-1.645 \frac{12}{\sqrt{50}}</span>
